Tropical cyclones (TCs) are intense low pressure systems where the wind speed in the surface circulation system exceeds 33 nautical miles per hour (knots). The low-pressure systems over the northern Indian Ocean (NIO) are classified (Table 1) on the basis of associated maximum sustained surface wind (MSW) at the surface level. Systems with the intensity of depressions and above are considered cyclonic disturbances. TCs occurring over the north Atlantic Ocean are known as hurricanes and those occurring over the Pacific...
